Cable router vs modem and wireless router

Hi everyone,

For a long time I use to get internet from my ISP modem and I used my own WiFi router to get WiFi to devices. But most recently I got Spectrum service with cable and the ISP installed and Arris router that seems to be a modem and wireless router because I had never seen a wireless router with a coaxial cable. I was so used to seeing the coax in a modem and then Ethernet from it to a wireless router. Now, the question is if I'm able to remove the Arris and place my own modem and plug and Ethernet from it to a wireless router. Or is there a special set up I have to do or permission from ISP

You have to get permission. There are long discussions

So I'll keep it short. When you install your new modem there is a call to the ISP (Spectrum) to enable it. They used to only ask for the MAC address but be prepared for more questions.

Most folk use what was installed and add their own router for what reasons they needed the new router for. Some will just try it without configuration of the ISP gear, some will set the first cable/modem router to bridge. Since bridge mode is widely discussed I stop here.

I will look into bridging

Thanks for informing me. I'll look into bridging. I was also wondering if there was an advantage/disadvantage to having modem and router separate such as possible bottle necking, etc. I will search on!

My experience

Is the combo units have lower performance than discrete modem (or combo in bridge mode) and your own router.

These combo units are under severe pressure on pricing so it's a sure bet they don't deliver the best performance.

No need to remove Arris hub

In reply to: Cable router vs modem and wireless router

Most cable providers in the US like Spectrum and UK Virgin Media, now use a hub which integrates router and modem and wi-fi. So co-ax connects to this hub which proivdes DHCP, security and wi-fi. There is no reason to remove the Arris hub. If you really wanted to and you what you are doing, you should be able to logon to your arris hub and go into advance setting and set it to modem only. Once done you can connect your wifi router via CAT5 ethernet and configure your Wi-fi router to issues IP addresses and security features etc.
